Notes:

Measured & Indicated resources include Proven and Probable Reserves.

Batman and Quigley Resources are quoted at a 0.40g-Au/t cut-off grade. Heap Leach resources are the average grade of the heap, no cut-off applied.

Batman: Resources constrained within a $1,950/oz gold pit shell. Pit parameters: Mining Cost $3.00/tonne, Milling Cost $17.50/tonne processed, G&A Cost $1.50/tonne processed, Au Recovery metallurgical equation averaging 89.7%.

Quigleys: Resources constrained within a $1,950/oz gold pit shell. Pit parameters: Mining Cost $3.00/tonne, Milling Cost $17.50/tonne processed, G&A Cost $1.50/tonne processed, Au Recovery metallurgical equation averaging 89.7%.

Differences in the table due to rounding are not considered material. Differences between Batman and Quigleys mining and metallurgical parameters are due to their individual geologic and engineering characteristics.

Kira Johnson, MMSA, of Tetra Tech is the QP responsible for the Statement of Mineral Resources for the Batman, Quigleys deposits and Heap Leach pad.

The effective date of the Heap Leach, Batman and Quigleys resource estimate is July 25, 2025.

Mineral resources that are not mineral reserves have no demonstrated economic viability and do not meet all relevant modifying factors.

The Mineral Resources were estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) Definition Standards for Mineral Resources and Reserves.

Notes:

The Mineral Reserves point of reference is the point where material is fed into the processing plant.

Batman deposit Mineral Reserves are reported using a 0.50 g Au/t cutoff grade and $1,800/oz gold price.

Colin McVie, FAusIMMand Peter Lock , FAusIMM of Mining Plus are the QP's responsible for the Statement of Mineral Reserves for Batman Deposit Proven and Probable mineral reserves.

Because all the heap-leach pad reserves are to be fed through the mill, these Mineral Reserves are reported without a cutoff grade applied.

Deepak Malhotra SME registered member, is the QP responsible for reporting the heap-leach pad Mineral Reserves.

The effective date of the Batman and Heap Leach Mineral Reserves estimate is July 25, 2025.

Differences in the table due to rounding are not considered material

The Mineral Reserves were estimated using the CIM Definition Standards for Mineral Resources and Mineral Reserves.
